![]() ![]() The tendons of the fingers are held closely to the bones by a series of tissues called “pulleys.” When the finger is bent, the tendon must pass through these pulleys. The ring finger and thumb are most commonly effected, though the exact causes are not well known apart from forceful or repetitive hand injury. It is often accompanied by a click or pop with every movement. Trigger finger is when a digit becomes consistently locked or catches while bending or straightening. Surgery consists of cutting open the tendon sheaths, reducing friction and giving tendons space to heal. Treatment can be either non-surgical – consisting of immobilization of the wrist in a splint, over the counter pain medication, and physical therapy/stretching – or surgical. Then, bend your wrist down, stretching out the thumb side of your wrist – if you feel pain on the outside of the wrist, then you may have De Quervain’s tenosynovitis. Starting with a thumb’s up sign, tuck your thumb into your wrapped fingers and hold it tight. Anatomically, these tendons are covered by a slippery layer of tissue that can become irritated with repetitive strain (such as lifting a baby), causing friction and pain with thumb and wrist movements.Īn easy way to diagnose De Quervain’s syndrome is using the Finkelstein test. Common InjuriesĪlso known as “mommy’s thumb” or “texting thumb,” De Quervain’s tendinosis refers to a swelling of the tendons around the base of the thumb. Most evidence is anecdotal (even if compelling) – patients complaining of new pain or worsening pain with increased technology use – and larger scale studies are needed to establish a causal relationship between the two. This all said, it should be noted that the relationship between chronic cell phone use and hand and wrist injuries is not fully understood. Over time, this wear and tear can cause pain, swelling, and reduced mobility. Despite their gentler nature, the consistency of these technological motions adds up, leading to inflammation in joints and along tendons. Texting, typing, swiping, and scrolling all create repetitive stress on the hand and wrist – similar to sports like golf or baseball. How Texting and Typing Affect the Hand and Wrist 1 How Texting and Typing Affect the Hand and Wrist.This reduces required maintenance because the owner won't have to manually adjust the clamps as they wear over time, being careful not to over-tighten them. Instead of static clamps as on the single-action version, moving arms with spring-loaded down pressure maintain optimal contact between the knives and the ledger plates. Self-adjusting tensioners are a key feature of all Dual Action Sickle Bar Mowers.It can also be used for forage harvesting, most notably hay. Both versions of the Dual Action Sickle Bar are much wider than the wheelbase, so you can easily trim along slopes, ponds, under fences, and other low-clearance places you wouldn’t dare take a traditional mower.Compared to the standard sickle bar, it reduces vibration and enables mowing large grassy areas at faster speeds. The version with fingers is formerly known as "duplex", and has been available for many years.Featuring riveted guards on the lower teeth to allow for no clogging of mowed materials, and have spring-loaded blade tensioners for decreased vacillation.The dual-action reduces vibration for the operator and increases efficiency in mowing applications. ![]() This unique and fast sickle bar attachment mows using two moving blades, each moving in equal and opposite directions. The BCS Dual Action Sickle Bar Mowers step it up a notch from its single-blade predecessor. ![]()
